    Classification and research of the reactor protection instrumentation and control system functional safety Markov models in a normal operation mode
    (CEUR-WS, 2016) Bulba, E.; Ponochovnyi, Y. L.; Sklyar, V.; Ivasiuk, A.
    This article presents the basic phases of the development and research instrumentation and control system (ICS) functional safety Markov models on the basis of the self-diagnosing programmable platform. The set of the models sets is obtained on the basis of the failure tree development and analysis, which includes the ICS hardware channels detected and undetected failures. There the classification of ICS in a normal operation mode, considering the different majority body modes and diagnostics levels is presented. The application of the models has allowed determining the boundaries of the ICS safety integrity level 3 (SIL3) in two-dimensional space of the input parameters and system operational time. © 2016 by the paper authors.

    Influence of diagnostics errors on safety: Indicators and requirements
    (Institute of Electrical and Electronics Engineers, 2018) Ponochovnyi, Y. L.; Bulba, E.; Yanko, A.; Hozbenko, E.
    In article questions of intersection of indices of technical diagnostics and the functional safety are considered. The relevant standards on diagnostics (IEC 60706-5-2007) and the functional safety (IEC 61508-4:2010) determining indices of a completeness and reliability of diagnosing, a share of safe failures and spanning by diagnostics are defined. Requirements to indices of the functional safety for achievement of the necessary level of a completeness of safety of electronic systems are selected. Influence of errors of system of diagnosing on indices of the functional safety is considered that allows to specify their assessment before carrying out evaluation tests.
